QXL-TESTING APARATUS.

To all whom it may concern:

Be it known that I, PAUL i'veNn'r, a citizen of the free town of Lbeck, and resident ot' 4 Hinter den Heeten, in the tree town ot Hamburg, German Empire, have invented new and useful Improvements.in Oil-Testing Apparatus, of which the following is a specification.

This invention relates to an improved process and apparatus for testing oils in the presence of steam, gases, hot air or the like and the object is to ascertain whether the oil supply to the gas or fluid is taken up in such a manner thereby that it is finely divided therein or whether a complete separation takes place.

The invention also enabl Y the character oi the oil when mixed with the`gases or fluids to be asccrtai ned.

According to the present inventionai'ter the oil has beenosupplied to the aas, fluid or the like, the mixture caused to traverse over a comparatively lonepath and any con stituents thereof tending` to deposit, settle down during the traverse ot the mixture. The mixture is supplied to a container. within which means are provided tor causingr the mixture to pass over a eomparatively lonja' path in said container betere obtaining' exit therefrom, the deposits settling` within the Walls of the container, which is so construct'- eol that it may be readily inspected over its whole length, so that the amount. ol the deposit and the length of surtaceovor which the same extends can be readily ascertained and, if'desired, the. deposits may'fhen iuniorgo'further tests in a suitahlefapparatns.

In order that the invention may he more. clearly understood reference is made to the accompanying drawings. whcreon is shown by Way of example the i'nelt-,rrcd method o'l,` carrying out the invention.

Figure l` is aj'crtical section tl trough the 'o1l-testing apparatus, Fig. 2 is ai 1 clevatitm partly in section ot the inner container and' 1s a plan View of Fig. l. with the cover o removed.

' The apparatus comprises a chaml'ier flo the Walls of which aire ot suitable thickness and material in orderfto` protect. the same t' heat radiation and is provided with a cover c'. 'Within the chamber w is fitted a coutainer'a preferably of cylindrical form, this container being provided with a cover' a? ialrdlhaving an .inlet f thereto, this inlet f Speeiication o Application filed April 2?, l.

l connnunicating with the inlet s of the chamber w, being' provided ywith a conical head m fitting" within the bore-hole. of the inlet connection s, the connection being maintained by means of a wedge 7c inserted between the wall of the chamber w and the container a. The chamber 'w is also provided with an outlet connection e and a thermometer or the like The cover d of the container a is removable but is secured against displacement during testingr operations viz.: by means of a spring w secured to the cover o of the chamber w. Within the container a are located two inrer bodies and o bot-h of which are provided with eX- ternally projecting ribs n, 0 arranged 1spirally around the same, the breadth of the ribs n., o being such that the ribs u bear against the outer wall of the container a and the ribs o against -tl1e ,ii1ner surface of the body Z).

The spaces between the ribs n and ribs o communicate with one another at their upper ends by way I the lower end of the spiral space formed by the ribs 0 communicates by way of an opening /L with a. central bore hole z' which is in conmiunication with a central hole p in the cover l and lateral apertures e in a boss ai on the cover d. The container' a preferably stands upon a layer of asbestos t, in the chamber on. I

lhc method oi" carrying" out the testing is as follows: After the oilhas been fed to the steam, gas or other tluid by a suitable f lropping arrangement, the mixture flows into the chamber w by way ot' the inlet connection s and inlet opening f into ,the spiral chamber between the container' a and the inner body` t) formed by the ribs;y n, and rising` therein, passes'through lthe opening g and descends in a spiral path through the space between the inner bodies and c formed by the ribs d, passing away there- 'lfroni through the opening` L to a centralv bore holo 27 escaping therefrom into `Jthe, chamber 'lo through the outlets e and passing away by way oi. the outlet connection z. According to the nature of thc mixtur constituents thereol'l tending to deposit, set` tile on the surfaces of the spiral path and the amount and` nature of such deposits may then be ascertained by removing the covers o and d and withdrawing the inner bodies and c, while at the same time the length e anyA over which such deposits extend may bel readily seen and, it desired, such deposits may be removed and subjected to further testing operations in any suitable testing machine.

It will be seen by the foregoing apparatus that a comparatively long path is provided for the mixture within a comparatively small space and that moreover the oil canE be subjected to the same conditions therein 1 independently of the nature of the. fluidl with which it is mixed.

As Will be seen lrom the drawings, the fluid is caused to pass upwardly between the container a and inner body and downwardly through the space between the inner bodies b and c in a spiral manner but, it' desired of course, the fluid may be caused to pass over a Zig-zag path within the container a although the construction hereint before described is preferable.
